Effects of surface forces and phonon dissipation in a three-terminal nano relay
L. M. Jonsson, T. Nord, S. Viefers +1
We have performed a theoretical analysis of the operational characteristics of a carbon-nanotube-based three-terminal nanorelay. We show that short range and van der Waals forces h…
Energy spectrum, persistent current and electron localization in quantum rings
M. Manninen, P. Koskinen, M. Koskinen +3
Energy spectra of quasi-one-dimensional quantum rings with a few electrons are studied using several different theoretical methods. Discrete Hubbard models and continuum models are…
Quantum rings for beginners: Energy spectra and persistent currents
S. Viefers, P. Koskinen, P. Singha Deo +1
Theoretical approaches to one-dimensional and quasi-one-dimensional quantum rings with a few electrons are reviewed. Discrete Hubbard-type models and continuum models are shown to…
Effective photon-photon interaction in a two-dimensional "photon fluid"
R. Y. Chiao, T. H. Hansson, J. M. Leinaas +1
We formulate an effective theory for the atom-mediated photon-photon interactions in a two-dimensional ``photon fluid'' confined in a Fabry-Perot resonator. With the atoms modelled…
